CONDUIT-PIPE.

SPECIFICATION forming part of Letters Patent No. 310,773, dated January13, 1885.

Application filed June 13, 1884. (No model.)

.To ctZZ whom it may concern.-

Beit known that I, THEODOEE BAcMEIsTER, of Toulon, in the county ofStark, in the State of Illinois, have invented an Improved Conduit-Pipe;and I do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the annexed drawings, makinga part of this speci-` cation, in which like letters of reference referto like parts, and in which- Figure l represents a side view of theinvention; Fig. 2, a cross-section of the same; Fig. 3, a side view of amodified form of the invention; Fig. 4, a cross-section at x e in Fig.3; Figs. 5 and 6, transverse sections of the two forms of pipe, showingmodes of putting-the bands thereon.

The object of this invention is the adaptation of wooden piping toreceive metal strengthening-bands and permit them to be tightened aboutthe same.

My invention consists, essentially, of a pipe having its exteriordiameter alternately increasing and diminishing regularly from end toend, whereby encompassing me? al bands may be driven from the smaller tothe larger parts of said tube.

In thedrawings, Arepresents the pipe, and B the bands surrounding thesame. a a are the parts of larger diameter, and a athe parts of smallerdiameter. In Fig. l the increase of diameter is equal on both sides ofeach contracted part a', while in Fig. 3 the increase is gradual at oneside and sudden at the other. Of these two forms I design the latter tobe that usual for wooden piping bored from the solid, while the firstform is preferable for tubes made in sections.

In making pipes from solid timber it is a simple operation to turn themupon a lathe and form them with either sudden or gradual changes ofdiameter; but when making a pipe with separate strips or staves saidstaves have to be formed by means of a planer or sticker, and the grainof the wood and manner of working it forbid anything but gradualthickening and thinning of the sta-ves.

In putting together sectional piping all the staves but one are firstinserted in the different bands B. Then, the bands lbeing at thedepressed places of the staves, the l latter are spread outwardly until,between the first and last of the same, there is room for the last ofthe staves to be crowded in under the bands. Fig. 5 shows the stavesspread apart in the bands to make room for the last one. When the pipesare formed from the solid,thebands B must be united when about the same.To

do this each band B is passed about the pipe being less than the greaterdiameters of said` pipe and greater than the lesser diameters of thesame, substantially as and for the purpose specified.

2. A pipe, A, having its diameter alternately increasing anddiminishing, substantially as set forth, in combination with metal bandsB, for the purpose herein described.

3. In a conduit-pipe, a pipe, A, formed of several strips or staves,each of which has the alternate elevations and depressions a a, incombination with the metal bands B, as and for the purpose herein setforth.

In testimony that I claim the foregoing invention I have hereunto setInyhand and seal this 9th day 0f J une, 1884.
